MOLD FOR FORIVIINO BOOT OR SHOE- HEELS.

SPECIFICATION forming part of Letters' Patent No. 322,301l dated July14, 1885.

Application filed May 2, 1885.

T0 all whom, it may concern: 1

Be it known that I, EDWARD J. LE GAY, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Molds for Making Boot and Shoe Heels, which will, inconnection with tlieaccompanying drawings, be hereinafter fullydescribed, and specifically defined in the appended claims.

This invention has for its object the production of molds by which tomold, fromsuitable moldable material, a shell or wall for the heels ofboots and shoes, and also, after such shell or wall is properly driedand set to form, to mold, compress, and set therein a filling-block ofwood or other suitable material and an interposed layer or body ofadhesive cement, which firmly connects together such outer wall and itsfilling-block, all as by aid of the accompanying drawings will behereinafter described and claimed.

In said drawings, Figure 1 is a'plan view of the respective parts A B Cof the mold, the same being shown as disconnected, but in properrelative position to be assembled or connected together for operativeaction. Fig. 2

is a longitudinal central vertical section of part A of the mold, takenon line X X, Fig. 1. Fig. 3 is an end elevation of said part A, taken asviewed at the right in Fig. 1. Fig. 4 is a side elevation of said partB, taken as viewed fromthe near side in Fig. 1, or as viewed from thelower end of the sheet. Fig. 5 is an elevation of said part C, taken asviewed from the left in Fig. 1. Fig. 6 is an elevation of said part C,taken as viewed from the near side in Fig. 1, or as viewed from thelower end of the Sheet. Fig. 7 is a side elevation of part D of themold, which replaces part B when inserting the wood iilling in thepreviously-molded shell of the heel, said view corresponding to that ofpart B in Fig. 4. Fig. 8 is a transverse vertical section taken as online Z Z, Fig. 1, but showing the respective parts of the mold and themolded outer wall of the heel in their proper relative positions. Fig. 9is a longitudinal vertical section of the parts shown in Fic. 8, takenas on line x as, Fig. 1. Fig. 10 is an inverted or underside plan viewof the compressor employed with my mold. Fig. 1l is a view like Fig. 9,but

(No model.)

showing a change in the form of the molds for overarched breasts of theheels, and an iml part of cavity a in body A, and to act upon theinterior of the shell or wall of the heel when being molded in saidcavity. Abase-or An interior mold, B, is` lformed in its upper portion cas a counterlower portion, d, of said mold B Iills the lower portion ofthe cavity in exterior mold, A, in which, for convenience ofconstruction, the

cavity is carried directly through from `top to bottom. l

For the purpose of molding the breast of the shell of the heel, Iemployl the follower C, which by its lugs f is interlocked in grooves gof mold A, and which is formed with an overhanging portion, h, which,when the several parts ofthe mold are brought together, extends over theprojecting lower portion j of mold B, as shown in Figs. 9 and 11, thelower portion z' of the follower being then close to part d of said moldB.

For the purpose of parts of the mold together aft-er the blank hasforcing the respective been inserted therein for molding, I employ astrong metallic hoop or clamp, E, whose longer sides Ic k are verticallyparallel, (as are the side walls of the mold,) but whose ends ZZ are yis then forced downward upon the mold by a cap, a, actuated by plunger pof a press, or by other effective means. the clamp E forcing the partsof the mold together by the action ol' the described inclines tilltheblank is y molded tov the eXact form of cavity a in outer mold, A, andof portion e of interior mold, B, and the adjacent faces of the breastof said portion c and corresponding part of portion n, as shown in Figs.8, 9, and 11.

As above stated, the rear and side walls of the heel-shell are moldedbetween molds A and B, the breast is molded between B and C, and thebottom between B and cap n. As shown in Fig. 9, the breast of the heelis a right line, while in Fig. 11 it is formed with an overarchingcurve.

For the purpose of securing the heel-blank in position, while parts A BG of the molds are being forced together by clamp E, I arrange in stem pof cap a a spindle, 8, which is secured by pin 9, passing through a slotin 8, as indicated by dotted lines, and so as to allow said spindle tobe thrust out by the action of spring 11 to the extent of said slot, sothat before the cap a is in contact with clamp E the foot on spindle 8will engage the part of the heel-blank b which is folded over the upperface of B, and by the action of said K spring will secure the same inposition till cap f been placed therein, it is necessary to subject thesaule to moldingpressure, in order to give the requisite seat in the topfor the heel of the wearer 5 and as part B cannot be employed for suchpurpose I provide part D, the lower part of which corresponds to part dof B, while its upper portion 7 is of the proper contour and relief toduly form the seat for the heel of the wearer.

In my application No. 152,947, filed Jann ary 15, 1885, are shown heelssuch as my molds are especially adapted to produce; and I re fer to saidapplication and the patent that may issue thereon as illustrating theproduct of the molds herein described and claimed.

I claim as my invention- 1. A heel-mold formed with part A, having` arecess, a, corresponding to the rear and side walls of the heel, part B,having portion c of a size and form corresponding to the cavity in theheel-shell when it is i nsertedm in cavity a, and follower C, formedwith part h, corresponding to the front of part B, substantially asspecified.

2. The combination, with parts A C of a heel-mold formed as specified,of cap D, having portion 7, adapted to t and forni the concave upperface of the heel-iilling when molding the lling-block and cementtherein, sub stantially as specified.

8. The combination, with a mold formed with parts A B C, having form andadapta tion to mold and set to form the shell or wall of boot and shoeheels, and with parts A and C, having oblique outer ends, as specified,of band or clamp E, having corresponding internally-oblique ends, andadapted to force together the respective parts of the mold and position,substantially as speciiied.

5. rIhe combination, with parts A B C of the heel-mold, clamp E, andplunger p, with its cap n, of sliding stem 8, its foot 10, and extendingspring 11, all substantially as speciied.
